WAX DISTRIBUTOR FOR FLOOR-POLISHING MACHINES.

Application filed December 22, 1925.

.lriy invention relates to an improvement in Wax distributors for floor polishing Inachines.

In floor polishing machines where cans of preparedwax are inserted in the rotary brushes, difliculty has sometimes been experienced in forcing the entire wax content of the can out into the brushes, or upon the floor, or both; and it has happened in some instances that wax ceased to issue from the can while in the machine. Upon removing the can it was found it still retained an appreciable amount of liquid wax.

The sole purpose of my invention is to obviate that objection and insure the discharge of the entire contents of the can while the machine is in operation.

This invention consists in a can, the bottom of which is provided with a dimple. It further consists in a can having a dimpled bottom with a rounded lower edge with holes through which the contents issues upon rotating the brush.

Inthe accompanying drawings:

Fig. 1 is a plan view of the brush showing the can in position;

Fig. 2 is a View of the same in vertical section; and

Fig. 3 is an enlarged sectional view 30 through the can.

A, is a brush having a central orifice 1..

C, represents the can adapted to contain the liquid wax, it being made to slide into the orifice l of the brush with a rib or other means to prevent its turning therein, and having a removable cap or cover 3. A dimple 4 is formed centrally in the bottom of the can, and the outer edges 5 are rounded and provided with no less than two oppo- Serial No. 76,983.

sitcly located pin-holes G for the discharge of the contents upon the floor and into the brush as the brush is rapidly rotated in the brushing and polishing of the tioor.

In this way, there is no chance of the contents oi the can remaining on the bottom, and the tendency (due to the centrifugal action) is to force it to the rounded corners. In other words, the bottom is formed on a scientific principle to insure the discharge of the entire contents oi the can, thus avoiding waste which would otherwise result by failure to make available and get the benefit of the entire contents of the can.

A cap 7 is removably placed on the bettom to prevent the escape of wax when the can is not in use. The cap is, of course, removed just before the can is inserted in the orifice l.

I claim:

1. A wax distributing can for use in a brush provided with a head and bristles carried thereby, said can having a dimpled bottom, provided with a rounded outer edge, said rounded outer edge having a discharge opening therein for discharging of the contents laterally onto the bristles.

2. A War distributing can for use in brush provided with a head and bristles carried thereby, said can having a dimpled bo tom, provided with a rounded outer edge, said rounded outer edge having discharge openings therein extending in directions transverse to the direction of the bristles for discharging the contents laterally onto the bristles.

In testimony whereof I aiiix my signature.
